I've been working on a full undertale game. But I wanted to remix it.. Can anyone help me? Please?
EDIT: I don't wanna make a new account ;-;

i don't know if this will work on your computer, it didn't on mine. try signing out then go in your own project, click remix, then sign in.

You could just press ‘File’, then, ‘Save as copy’. Like this:

It's a lot simpler than remixing. However, if you want it to actually show up as a remix when you share it, so it gives a link to the original project:
1) Make a new tab.
2) Open your project in this tab.
3) In another tab, go to the Scratch homepage and sign out.
4) Press remix in the tab displaying your project!

Thanks guys!
